Embodiment Construction

[0014] Such as Figure 1 to Figure 4 shown. The optical glass primary thermoforming device of the present invention is composed of a bottom mold 2, a bottom mold transmission device 1, a side baffle 6, scrapers 7, 13, a burner 3, a spray gun 4, a leakage pipe 5, a cooling pipe 8 and a storage device 10. . Wherein, bottom mold 2, side baffle 6, scraper 7, 13 select superhard heat-resistant alloy to make for use. The bottom mold 2 is formed by a plurality of narrow and long modules closely arranged, and the adjacent modules are hingedly connected, and the end to end is connected in a ring-shaped crawler pattern, and the number of connected modules is determined by the glass grade to be produced. A sinker is formed on the bottom mold 2 according to the appearance shape of the prefabricated part to be formed, and a plurality of modules are closely arranged to form a complete sinker 11 . The side baffle 6 is a pair of two pieces, arranged above the both sides of the annular modu...

Abstract

The invention relates to a once thermal molding device of optical glass, belongs to the technical field of optical glass molding, and mainly solves problems comprising high optical glass waste existing in small-molding-viscosity, short-material-property and easy-crystallization optical glass, and long production period and high cost of optical elements in the present production. The device is mainly characterized in that the device comprises a bed die, a bed die transmission apparatus, side shields, scarper plates, a burning gun, a spray gun, a leaked material tube, a cooling tube and a receiver, wherein the bed die is formed by a narrow and long module group with the modules connected through hinges and tightly arrayed in an annular mode, and the module group is provided with a sinking groove corresponding to glass preforms; the bed die is connected with the bed die transmission apparatus; the burning gun, the spray gun, the leaked material tube, the side shields, the scraper plates and the cooling tube are sequentially arranged above the annular module group; and the receiver is arranged under the side part of the annular module group. The device has the characteristics of continuous production, consistent appearance and shape, and consistent weight, and is mainly used for producing the optical glass preforms having the shortages of small molding viscosity, short material property and easy crystallization.

Description

technical field [0001] The invention belongs to the technical field of optical glass molding. It specifically relates to a device for one-time thermoforming preforms of a type of optical glass that is poor in stability, poor in melting, and extremely easy to devitrify at high temperatures. The forming device can be used to inject molten glass with a molding viscosity of only 1.5 to 3 poises. mould, and rapidly cooled to shape. Background technique [0002] With the upgrading of digital products and the rapid development of logistics networks, various optical lenses and camera viewfinder lenses are developing in the direction of large wide-angle, small size, and high resolution. Make optical glass with high refractive index, low dispersion and high transmittance the first choice for optical parts. For optical glass materials to have the above properties, a large amount of rare earth elements and Zr, Nb, Ti, Ta, Sr and other elements must be introduced into the glass composi...
